S Ciaims;

This invention relates to rear luggage compartment locks for automobiles. 1t is desirable to have a lock which will tension the parts and draw the lid tightly down upon the frame or jamb of the compartment opening to give a weather-tight seal with the weatherstrip and also to make the body rattle-procf- `Locks with hook-like latches that are caused todraw into engagement with the keeper havev been proposed and used. These accomplish the objective above referred to but they have been objectionable for the reason that they protrude from the lid When itis raised and many people have received bumps and injuries by not observing the protruding latch when they bend over to reach into the compartment.

It is the object of the present invention to provide a lock which will draw the lid tightiy shut and which, at the same time when the lock is released, will draw up out of theway and retreat beyond the edge of the lid. ThisV lock operates positively by means of pin and cam slots to be disengaged from the keeper member and to be Withdrawn out of the way. This is important, if there is any luggage in the waywhen it is Sought to open the lid. The bolt is definitely maintained `in unlockedposition out of the way by the relationship of the slots to the pins, The lock described and claimed in the following specication is the lock which will reliably achieve the objectives heretofore stated.

Referring to the drawings:

Fig. 1 is a longitudinal section through the lock showing the lid lock closed, taken on the line I-I of Fig. 2.

Fig. 2 is an elevation of the lock.

Fig. 3 is a section on the line 3 3 of Fig. 4.

Fig. 4 is a longitudinal section on the'section line 4 4 oi Fig. 3 and similar to Fig. 1 butA showing the lock released and the locking arm withdrawn.

Fig. 5 is a plan View of a modified form in which two of these locks are used on a lid with the' common actuating member on the up and down centerline of the lid.

Fig. 6 is an elevation oi the modied form.

Referring to Fig. 1: I designates the rear compartment lid, 2 the body adjacent the rear compartment opening, 3 the jamb of the rear compartment opening, 4 a weatherstrip of soit, easily deformable rubber, such as sponge rubber, 5 the overlap flange oi the lid and (iY the keeper or stationary hook that is bolted to the inside of the compartment by the bolt 1.

The locking parts are actuated by a handle shaft 8 Which is operated by a handle 9'. On the end of this handle is a crank I0 connected by link II with slide I2. This slide is provided with flanges I3 to aid in guiding the slide in the casing I4 of the lock. Turned over ears I5 hold the slide in place. The flanges' I3 ofl the slide are provided with longitudinalslots I6 in Which-en gages apin I1 which is provided with a headf at eachl end to hold the parts assembled. Thispin is fixed to the locking arm I8'. A's'econd' pin-|-9 passes through the iianges I3 and isiixedvto the lock casing and is held in-pla-ceby the distortion of the'ends of the pinby punching; as at 20. This pinV I9- passes throughV cam slots 2fI- in theY sidesv off the,y locking arm'. The-locking arm hasa hooked end or bill 22 adapted-'to Iengage in `the'gullet ofthe hook-like keeper 6-- as shown in Fig. 1)

The operation'of` the parts is as ollevvstShaft 8 is rotated by handle 9. This -causes-lthe-parts to move rfrom the position shown inv Fig. 1-to that shown in Fig; 4, passing through the three dotted linepositions shown in Fig.- 4 tothe nal position shown in fulllinersfin-Fig; 4. The bill of,y the locking arm takes thepath shownV byl the arrowline'A in Fig. 4, While the lidV movesin the direction shownby` the arrow-B in`Fig-.-4. This-*movement ofr the-lockingv arm` isaccomplishedby theI action of -the two-pins` IflrandflA j in slots I`6and 2i respectively and -themove ment ofthe slidev I2 bymeans of crank arm I0 and, linkv I-i.' Slide I2moves-downwardlyffrom the-position-shown in Fig. 1. The-endorsint Hi picks-up pin I-'I-fifxed to the lock-ing armA 18; This pushes the locking arm down from the pfositiom shown in Fig. 11 to the positonXshown in dottedlines in Fig. 4. Inasmuch as-the lower end of the cam slot- 2i -is straight and-isV nearly,

parallel to the slot I6, thelmove-mentio the -bill of thearm --islargelyv a straight line movement, There is a slight angular component, as show-n by the arrow, due'tothe iactgthat a lowerportion of'slot' 2i is at a" slight angle-tojslot i8:

As the curved portion ofA slot' 2| 4reaches fthepini it moving along the Icurved portion of fthecamV slotj2'I"'towards vthe right hand end which is shownachievedin the full line showing of Fig; 4: in" this position, the locking arm is completely raised. `It has passed through a swing-ofv almost "and has been thrown up parallel with fthe wall ofthe lid and completely-beyondtheedge o the lid. In fact, it isswung up close tothe lid so asy to provide veryv` little projection `eVenon'the inside ofthe lid;V Thisjmakes the 'locking mem]- ber very unlikely to vcome'in contactrwithl' the head of one reaching into the compartment.

The locking of the member is just the reverse movement and it is to be noted that, in the final movement of the handle, the locking arm and the bill are pulled up in substantially a straight line pull into` a tight clamping engagement between the two hooks so as to firmly pull the overlap flange down against the deformable rubberV weatherstrip 4 and make a weather-tight seal and a rattle-proof joint.

The locks contemplated in Figs. 5 and 6 are the same. The only diiierence is that theY actuating handle 9 is put on the up and down centerline of the lid and the locks are put near the side edges of the lids so as to provide a better clamping and locking action than is had by a single lock at the center. The remote operating handle is connected with the cranks 23 on the ends of the operating shafts 24 of the locks. These connections are the long links 25 which are connected with the crank 26 that is attached to the handle operating shaft. Otherwise, the lock parts are the same.

What I claim is:
